Or, to the left, yes, it can be done, done quite successfully and with no ill effects to the snakes.
Of course, I am only on generation 12, yes TWELVE, where I have kept corns together. It hasn't worked with my milksnakes, sand boas, jungle corns or hognosed snakes either. I DO NOT have multiple generations of all those species.
If you're careful and observant, you can do it.
It can be done, but I just think that any risks outweigh the benefits, which the only benefits are for the owner. Not the snakes.
